Preface to Engineering Metrology and Measurements Book by N.V. Raghavendra and L. Krishnamurthy book.
Engineering Metrology and Measurements is a core subject for mechanical, production, and allied disciplines in all the major universities in India. Although there are a few good books available on metrology, the coverage of topics on mechanical measurements is either scanty or superficial, necessitating students to refer to different books on mechanical measurements. This book provides a comprehensive coverage of both metrology and mechanical measurements. Divided into three parts, the first part of the book comprising Chapters 1–11, begins with a comprehensive outline of the field of engineering metrology and its importance in mechanical engineering design and manufacturing. The basic concepts of engineering standards, limits, fits, and tolerances, for ensuring interchangeability of machine components are then discussed.

This is followed by a discussion on metrology of linear and angular measurements. Later in the book, comparators, followed by the metrology of gears, screw threads, and surface finish metrology are discussed. The chapter on miscellaneous metrology talks about laser-based instrumentation and coordinate measuring machines. The last chapter in this section features inspection methods and quality control. The second part of the book comprising Chapters 12–16 focuses on mechanical measurements. The coverage is restricted to measurement techniques and systems that are complementary to engineering metrology. The topics covered are the basics of transducers and the measurement of force, torque, strain, temperature, and pressure. The third part of the book comprising Chapter 17 details nanometrology techniques and instrumentation. Nanotechnology has opened a new world of scientific research and applications. India has also joined the bandwagon and today, we see a phenomenal investment in the research and development of this discipline, both in the government and private sectors. There is abundant scope for pursuing higher studies both in India and abroad. We hope this section on nanometrology will further stimulate the curiosity of the students and motivate them to take up higher studies in this new and interesting field. The book is designed to meet the needs of undergraduate students of mechanical engineering and allied disciplines. The contents of this book have been chosen after careful perusal of the syllabi of the undergraduate (B.E./B.Tech) and diploma programmes in India. The topics are explained lucidly and are supported by self-explanatory illustrations and sketches. The following are a few key features of the book.
